Description

BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The invention relates to a multiply foldable umbrella, in particular a locking device for opening an umbrella.

DESCRIPTION OF THE KNOWN DESIGN

At the moment the umbrella is opened in such a way that a slider is pushed upwards along an umbrella pole in order to open up the umbrella frame. With manual umbrellas, the slider must be positioned after sliding it up to keep the umbrella open. Usually an opening is formed on the umbrella pole in which there is a spring catch for supporting the slide. In the case of multiply foldable umbrellas, the umbrella pole consists of several tubular parts that are telescopically connected to one another. The pipe with the smallest diameter is called the inner pipe, whereas the pipe with the largest diameter is called the outer pipe.

There are two possible arrangements for the umbrella stick of the multiply foldable umbrella. In the first possibility of arranging the umbrella pole, the inner tube is provided at the top and the outer tube at the bottom, a crown being attached to the upper end of the inner tube, while an umbrella handle is attached to the lower end of the outer tube. In the second possible arrangement, the outer tube is provided at the top and the inner tube at the bottom, the crown being attached to the upper end of the outer tube, while the umbrella handle is attached to the lower end of the inner tube. With the second possibility of arranging the umbrella pole, the multiply foldable umbrella is top-heavy when used and does not correspond to the mechanical strength that is likely to lead to damage to the umbrella pole. Therefore, the best possible arrangement of the umbrella stick for the multiply foldable umbrella is the above-mentioned first arrangement of the umbrella stick. In the first arrangement of the umbrella pole, the opening for the spring catch should be formed on the inner tube, the inner tube having a small diameter and the opening on the inner tube slightly impairing the strength of the inner tube, making the inner tube easy to break. In addition, after the umbrella is opened, due to the small diameter of the inner tube, there is a large gap between the inner tube and the inner hole of the slider, which allows the slider to be shaken easily, resulting in an unstable opening of the umbrella. When the umbrella is closed, the spring catch has to be pressed, which can easily lead to cuts.

How the abovementioned missing problems are to be improved is therefore the technical point of difficulty which is to be solved by the measures according to the invention.
